Storage format and visualization for 2D carthesian grid in C++

ander · January 5, 2022, 16:20

Hi

I'm implementing a 2D cartesian Euler solver in C++. I have gotten to the point where I have to decide on how I am going to store and plot the data. My plan at this point is to run the simulation in C++, store it in some text format and then plot it with python's matlplotlib. Is there some standardized storage format that I should use? Or is it "acceptable" to just make up something that works? CGNS is a standard that I've heard about, but not sure if it would be unnecessary to figure this one out for my simple grid.

Thanks!

Take the chance to learn to write the output for an actual postprocessor. I suggest vtk or whatever paraview reads (say, ensight)
